...a pale (Greek chloros, pale green poisonous chlorine gas) horse:
and he that sat on him was Death,
and Hell followed with him.
And power was given unto them over the fourth part of the earth,
to kill with sword, and with hunger, and with death,
and with the beasts of earth.
Revelation 6:8



As for my flock, they eat that which you have trodden with your feet;  
and they drink that which you have fouled with your feet;

you have pushed all the diseased with your horns;

the diseased you have not strengthened,
neither have you healed that which was sick...

from Ezekiel 34:4,19,21



For nation shall rise against nation, and kingdom against kingdom: and there shall be famines, and pestilences, and earthquakes, in divers places. All these are the beginning of sorrows.  
Matthew 24: 7, 8
